What this MCCB carries on the nameplate
The Siemens 3VA2225-6KP32-0AB0 is a SENTRON molded case circuit breaker built for line protection — 3-pole, 250 A continuous current, with a breaking capacity range from 375 A minimum up to 2 500 A maximum. At 240 V it interrupts 242 kA; at 415 V and 440 V that drops to 187 kA, then 121 kA at 500 V, and 4.5 kA at 690 V. That voltage-dependent SCCR curve tells you where this breaker is comfortable — it's sized for 480 V and below systems where the fault current stays within those numbers. Thermal derating is published from 40 °C through 70 °C: it holds 250 A flat up to 50 °C, then steps down to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C.
The 3-pole footprint is standard for this class — it'll sit alongside other SENTRON 3VA frames without forcing a rail layout change. Two auxiliary switches HP come built in; no auxiliary release is fitted, so if you need a shunt trip or undervoltage release that's a separate add-on. Communication function is present, and it includes an 'other measurement function' — meaning it can talk to a higher-level system for monitoring, not just trip. No ground-fault monitoring version here, so if you need GF protection this isn't the variant.
